SEISMIC TIE FOR VIBRATION CONTROL OF BOILER, AND BOILER EARTHQUAKE-PROOF STRUCTURE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a seismic tie for vibration control of a boiler of a long service life.;SOLUTION: A seismic tie includes: two link members 16A disposed horizontally to a displacement direction; and two pin members 16B disposed vertically to the displacement direction. Both end portions of the link members 16A and the pin members 16B are connected by hinges. The pin member 16B has a bearing portion 16B-1 at a central portion in the axial direction, and a pin portion 16B-2 having an outer diameter gradually reduced from the bearing portion 16B-1 toward a hinge connecting portion 16C. The pin portion 16B-2 has an outer peripheral portion of the shape having a partially-recessed web portion 16B-3 and a flange portion 16B-4 formed on an outer edge side of the web portion 16B-3, and a thickness of the flange portion 16B-4 is gradually thinned from the bearing portion 16B-1 toward the hinge connecting portion 16C.;COPYRIGHT: (C)2015,JPO&INPIT
